China Launches World’s 1st ‘Hack-Proof’ Quantum Communication Satellite

China has taken one more step forward towards achieving success in Quantum communication technology.

China has launched the world’s first quantum communications satellite into orbit aboard a Long March-2D rocket earlier today in order to test the fundamental laws of quantum mechanics at space.

‘Hack-Proof’ Communications System

The satellite, dubbed Quantum Science Satellite, is designed to develop a ‘Hack-Proof’ communications system in this age of global electronic surveillance and cyber attacks by transmitting uncrackable encryption keys from space to the ground.

The 600-plus-kilogram Quantum Science Satellite, better known as Quantum Experiments at Space Scale (QUESS) satellite, took off from the Jiuquan Satellite Launch Center in Gobi Desert at 1:40 AM local time on a 2-year mission on Tuesday.

The QUESS satellite will help China perform unprecedented levels of experiments in quantum communication by sending entangled photons from the satellite to relay stations in China and Europe, which is separated by about 1,200 kilometers (746 miles).

The pioneering experiment is to test if the spooky property of quantum entanglement can work at long distances as well.

The satellite’s payloads include:

  • Quantum key communicator
  • Quantum entanglement emitter
  • Quantum entanglement source
  • Quantum experiment controller
  • Processor
  • Laser communicator

The payloads, designed to operate for two years, were developed by the National Space Science Center in Beijing under the Chinese Academy of Sciences.

The QUESS satellite will also test the possibilities of communication via quantum ‘teleportation,’ using an entangled pair of photons.

If the satellite is able to successfully transmit quantum information securely between two ground stations, it could have huge implications for encryption and cryptography.

China has largely been ambitious to realize the importance of Quantum technology. From past two decades, Quantum technology has been a top strategic focus in the country’s 5-year economic development plan.

While the United States invested about $200 Million a year in quantum research, China spent $101 Billion in quantum physics in 2015, up from $1.9 Billion in 2005.
